Attalus miniatocollis, Tarnier {I. c). (PI. XXIII. fig. 5.) 



A. niyer nitidus, parce 7iicjro pilosus ; capite piceo, bifoveolato ; tho- 

 race ritfo, quadrato, j^ostice valde rotundato, paullo convexo ; 

 elytris viridibus, parce punctat is, postice dilatatis ; pedibus nigris, 

 coxis anticis rufis ; antennis nigris, articutis 3 primis apice ru- 

 fescentibus. L. l^lin. 

 Mas. Antennis longitudine plus dimidio corporis. 

 Hab. In insulis Terceira et Tajal, in floribus copiose lectus ; in 

 ins. Santa Maria (Drouet). 



Nearly allied to the Canarian A. rujicollis, WolL, but distinct by 

 its punctuation &c. 



Phl(eophagus variabilis, n. sp. 



P. (Pneo-piceus ; capite parce subtilius punctat o, rostro substrigoso ; 



thorace antice subtilius, postice et lateribus fortiter punctata ; 



elytris grosse punctato-striatis , interstitiis irregulariter biseriatim 



punctatis. L.l^lin. 

 The above diagnosis will apply to nearly all the phages of this 

 variable species, which may be further characterized as follows : — 



Var. a. Thorax finely and sparingly punctured, very shining; 

 head extremely finely punctured ; elytra with the punctures in the 

 striae faint. From an elder-tree near the Furnas ; very rare. 



Var. /3. Thorax more coarsely punctured, but shining; elytra 

 with the punctures more deeply impressed, glossy asneo-piceous. 

 Very common in Euphorbia-stems in Flores and Corvo. 



Var. y. Thorax much more strongly punctured, especially behind, 

 so that the interstices between the punctures no longer glisten ; 

 elytra with the striae hardly deepened, so that the punctures stand 

 out isolated. Smaller than the last. Abundant in old trees in S. 

 Miguel. 



Var. h. The extreme form in this direction, with the thorax almost 

 scabrous, and the rostrum strigose. It is also smaller in size. In 

 old fig-trees. 



The above range of variation is paralleled in the Canarian P. lau- 

 rineus, which under similar circumstances runs through partly the 

 same changes. The lightly sculptured ones seem always attached 

 to the EuphorbicB. It is somewhat curious that in the allied 

 genus Mesites, where some are found on laurel and some on Eu- 

 phorbice, the two form distinct sections, instead of merely varieties 

 as here.
